Softonic review

Very good

I don't know when or where it was invented, but somehow Sudoku has come from nowhere to become one of the most popular ways to while away a journey. What's more, you don't even need a puzzle book to play it because there are so many versions of the game available for mobile devices.

Astraware's take on the format is very impressive and is actually one of the most well-executed I've seen anywhere. Obviously the scenario is the same as always - you have a 9 x 9 grid with a series of nine boxes and nine cells. You need to fill up all the cells with the numbers one to nine without repeating a number in any row, column or box.

But what's great about this game is the loving attention that's been given to its presentation. When you first start out, you're given an animated introduction to Sudoku, explaining all the rules in a succinct manner. You can then choose to start a new puzzle from the default ones built into the game, create your own puzzle, or download one from the Astraware site.

There are five difficulty levels to choose from, ranging from 'Beginner' to 'Diabolical,' which lets you develop your skills at your own pace. The in-game options are just as impressive. You can add pencil marks to assist you, get hints, change the display and set the level of assistance. Graphically, the game is tastefully presented and the board is very clear.
